CHARLES DAVID DOXFOBD, OF SUNDERLAND, ENGLAND.

TURRET OR SIMILAR VESSEL.

Application filed November 6, 1906.

To all whom it may concern:

Be it known that I, CHARLES DAVID Dox- FORD, a subject of the King ofEngland, residing at Sunderland, in the county of Durham, En land, haveinvented certain new and usefu Improvements in Turret or SimilarVessels, of which the following is a specification.

This invention relates to improvements in vessels ofthe well knownturret type shown in my prior U. S. Patent No. 485,462 in which theupper portion of the vessel is in the form of a continuous girdersomewhat narrower than the breadth of the vessel and extending over thewhole or the greater portion of the length of the vessel and providing alongitudinal strengthening frame or girder.

Previously I have invented a construction.

of vessel of this type in which the vertical stanchions and horizontalbeams formerly employed were dispensed with; but the constructioncomprised a number of specially strong webs and large lower gussetplates placed at intervals along the side walls of the vessel.

The object of the present inventionis to simplify the structure ofturret vessels of this type, and I have now discovered that all thenecessary strength or rigidity can be obtained in a turret vesselwithout any beams or stanchions and without any special webs or plates.

A turret vessel embodying this invention comprises a laterallyunobstructed main hull, transverse bulkheads dividing the hull atintervals, an upper portion of the hull in the form of a continuousnarrower than the main hu 1, and narrower internal frames extending fromtop to bottom of the hull and arranged to leave a clear unobstructed sace within the frames, with out any specia webs or lower gusset platesas hitherto used.

The accompanying drawing is a transverse section and perspective view ofone of Doxfords well known turret vessels embodying this invention.

Specification of Letters Patent.

irder somewhat Patented May 12, 1908.

Serial No. 342,235.

The turret A as usual is in the form of a continuous girder somewhatnarrower than the vessel and extending over the whole or the greaterpart of the length of the vessel. Thus the upper part of the vesselconstitutes in effect a longitudinal irder.

The side walls B are provi ed with frames 0. Large gusset plates Dextend from the frames O to the deck beams E at intervals in thoseportions of the vessel where the turret A merges into the side walls B,and these gusset plates are supported by brackets D and their thrustdistributed over a large area of the side walls: or these brackets maybe extended so as to form a continuous wide stringer plate. Between theframes C of the opposite side walls the hold is unobstructed; nostanchions, webs or large gusset plates being provided. The frames C areconnected to the double bottom F by knee plates G which occupy noimportant space in the hold.

The hull or lower part of the vessel constitutes in effect alongitudinal girder facin in a direction to the upper longitudinal girer.

What I claim as my invention and desire to secure by Letters Patent isIn a turret vessel the combination of a hull B, a turret A forming theupper part of the vessel and merging into the hull, deckbeams Eextending across the turret, a double bot tom F at the bottom of thehull, narrow internal frames 0 extending from the deck beams E to thedouble bottom F, leaving an unobstructed space from side to side betweenthe frames 0, large gusset lates D extending from the frames C to theeck E at intervals in those portions of the vessel where the turret Amerges into the hull B and small knee plates G securing the internalframes C to the double bottom F.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
